My battery door is missing.

make sure not to confuse the battery door with the audio cable cavity. when the audio cable is removed, there is a noticeable cavity at the bottom of the left earcup. this may be confused with the battery compartment at the top of the right earcup. be careful opening and closing the battery compartment door; it is not a replaceable part.

Left earcup

Right earcup

Note: When the earcup is folded flat for storage, the battery door is obscured by the headband yoke.
